Has anyone tried Salesforce or any other module with Jive Anywhere 3.0 on Chrome/Firefox ? We are seeing issues with discussion dialog not being closed after hitting POST button , dialog freezes after posting the discussion and you have to close it manually. It used to work fine with earlier JA version 2.3.1 and latest version has created this problem.

Yes, it does freeze on every page . I am surprised to hear that you weren't unable to reproduce the issue on your end. I was able to share my screen and reproduce this issue on Salesforce default 1.0 module with your colleague. WeCan reproduce this issue on existing places as well as new connections.
